Hi Community.
I have a SharePoint 2010 web part that uses Telerik ASP.Net Ajax UI and Skin component (version 2013.3.1114.35).
The skins work fine in the http site but fail to load in the https site. Identical web.config in both sites.
Same Telerik.Web.UI.Web.Resource.axd version in both http and https site under teh <handlers> and <httphandlers> sections in web.config.
I debugged and the Telerik API 'GetEmbeddedSkinNames' in http site retrieves all skins and return none in https so it falls to 'Default' skin.
In the C# project the both Telerik assemblies (Telerik.Web.UI and Telerik.Web.UI.Skins) have 'Specific Version= true' in the dll property window.
In the WFE server's GAC there are multiple Telerik assemblies (3 Telereik.Web.UI and 2 Telerik.Web.UI.Skins - the version I use is the latest registered in the GAC.
Just to make everything else even more confusing, in the test site (replica of Production) http and https work fine both.
Any idea? I'd try everything that you suggest me as I hit a point that I have no more ideas (and energy) to work on this! :)
Thank you and Happy Holidays!
